In a classic “What took them so long?” move, several stars from ABC’s prime time musi-soap “Nashville” are going on a three-city mini tour that hits New York’s Best Buy Theater (1515 Broadway) on May 6. Tickets go on sale April 4 at axs.com.

First we have the show’s four main guys, starting with Charles Esten, who plays our favorite recovering alcoholic-slash-cult guitarist, Deacon Claybourne.

Chris Carmack (closeted hunk Will Lexington) is the closest the show comes to delivering an actual Music City-style hunk. And like several of his co-stars, Carmack’s already proved he can actually handle the Grand Ole Opry.

Jonathan Jackson’s Avery Barkley has undergone such a dramatic personality transplant between series 1 and 2 that it qualifies as a medical miracle. What hasn’t changed is Avery’s sweet, sweet guitar-playing, which he demonstrates by backing pretty much everybody on the show — including tourmate Sam Palladio (pompadoured Gunnar Scott).

Tamping down the testosterone is Clare Bowen (simpering artiste and budding pill-head Scarlett O’Connor), possibly the show’s most annoying character — though blessed with an angel’s voice. Scarlett may have thought a number like the rowdy “Crazy Tonight” was beneath her, but it was great to see her perk up for a change.

Joining them for the New York date only is Will Chase (mega-popular country star Luke Wheeler), an actor with extensive stage experience — in musicals. Chase has scruffed up very nicely for “Nashville,” taking to his adopted genre’s tight pants and black hats with impressive ease.
